The U.S. Mint said Wednesday it will suspend sales of the popular American Eagle 1-ounce bullion coins as rising demand depleted its inventory.

“The United States Mint has depleted its current inventory of 2009 American Eagle 1-ounce gold bullion coins due to the continued strong demand for this product,” the Mint told its authorized dealers in a memorandum on Wednesday.

November sales to date were at 124,000 ounces, higher than the 115,500 ounces sold in each month of September and October, the Mint said.
